In order to find some guidelines for adequate examination of the often very large amount of tissue removed at reduction mammoplasties, a thorough macro- and microscopic study of a total of 400 specimens from 200 consecutive cases of bilateral breast reductions was done. The majority of patients were younger than 30 years of age. In these cases no abnormalities were found and a thorough macroscopic
Popular Abstract in Swedish Signalen som registreras under ett arbets EKG prov kan innehålla viktig information rörande hjärtats kondition. De störningar som ofta uppträder i signalen kan dock försvåra en korrekt diagnos. I avhandlingens första del används tidsserie modeller för att skatta profilen, den del av signalen som härrör från hjärtats elektriska aktivitet. Målet med dessa metoder är att The analysis of the recorded electrical activity of the heart during an exercise test is a valuable method for investigating a patient's circulatory and respiratory system. But the disturbances that occurr during a test often make it difficult to interpret the signal in order to detect changes evoked by the increased workload and related to for instance coronary artery diseases. Suppression of dis
Various kinds of subgraph counts have been proposed as important statistics in the social sciences: for instance, in connection with studies of the structural properties of social networks. Since the empirical structure in question often involves an element of randomness, subgraph counts are random variables and, consequently, we need to describe their probabilistic properties. In this paper we gi
Why, how, and with what consequences do national governments delegate political authority to supranational institutions? Contrary to the static conceptions of delegation that dominate the existing literature, this article adopts a dynamic approach, where the stages of the delegation process are integrated into a coherent rational institutionalist framework. With demonstrations from the case of the
AbstractAquaporins are membrane integral proteins that facilitate the transport of waterand/or other small neutral molecules across biological membranes in cells in allforms of life. Among the subfamilies of aquaporins in higher plants, the X IntrinsicProteins (XIPs) are the most recently discovered subfamily and the leastcharacterized. However, the aromatic/arginine (ar/R) selectivity filter and
Blood development relies on discrete stem and progenitor cell populations with unclear lineage relationships and distinct functional characteristics that change during ontogeny. In this issue of Cell Stem Cell, Beaudin et al. (2016) identify a hematopoietic stem cell population with fetal characteristics that is developmentally restricted yet capable of long-term multi-lineage reconstitution upon
A 66-year-old man with type 2 diabetes on hemodialysis treatment was admitted due to poor glycemic control. His serum insulin level and the 125I-insulin binding rate were extremely high with an increased eosinophil count, although he did not have an allergic reaction to insulin or an elevation of specific IgE for human insulin. A Scatchard analysis revealed that the patient’s insulin antibodies ha
In the present study direct microcalorimetry has been employed to measure heat production of blood plasma and blood cells at basal and activated stages. The energetics of granulocyte activation.....
It has been demonstrated that PID controllers can be tuned effectively based on an experiment with relay feedback. This paper describes a tuning method for a general digital controller based on relay feedback. The control design method is based on pole placement. An interesting feature is that the sampling period and the desired closed-loop poles are determined from the experiment. The method is a
Distance relays are one of the most important components of protection available to power system protection engineers. Distance relays can benefit from ideas in the newly developed field of adaptive protection, and can offer an even more selective and sensitive form of protection, under a variety of power system configurations. A new fast adaptive distance protection scheme for single line to grou
Background: The SYNAPSE study (NCT03085797) demonstrated that mepolizumab decreased nasal polyp (NP) size and nasal obstruction in patients with chronic rhinosinusitis with NP (CRSwNP). Methods: SYNAPSE, a randomized, double-blind study, included patients with recurrent, refractory, severe CRSwNP, eligible for repeated surgery despite receiving standard of care (SoC). Patients received 4-weekly me
In post-quantum cryptography (PQC), Learning With Errors (LWE) is one of the dominant underlying mathematical problems. For example, in NIST’s PQC standardization process, the Key Encapsulation Mechanism (KEM) protocol chosen for standardization was Kyber, an LWE-based scheme. Recently the dual attack surpassed the primal attack in terms of concrete complexity for solving the underlying LWE proble
Despite their emancipatory aspirations, collective entrepreneurial efforts to change organizations bottom-up are often complicit with the power structures they seek to transform. Our study takes a closer look at how workers experience and deal with the tensions between emancipation and complicity and how this can inform the entrepreneurial process. Empirically, we draw from a qualitative single-ca
